Alan B Campbell, Andrew McKee, Sanford Cobb Jr, Wade D Kretman: Optical film with defect-reducing surface and method for making same. 3M Innovative Properties Company, William D Miller, November 27, 2001: US06322236 (113 worldwide citation)

An optical film has surface that reduces the occurrence of optical defects in a display using the film. In particular, the surface has randomized characteristics that reduce such defects as wet-out, Newton's rings, and Moiré effects. The film has a first surface free of regular structure, the f ...

Andrew J Ouderkirk, Michael F Weber, James M Jonza, Carl A Stover: Optical polarizer. 3M Innovative Properties Company, William D Miller, August 1, 2000: US06096375 (93 worldwide citation)

A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two ...
